Fig. 37 is a detail view of a modified form of needle.

By referring to the drawings, it will be seen that the device includes a stationary supporting structure 10, and an upper and a lower. transversely movable structure 11 and 12, respectively. The movable structures 11 and 12 are united and are adapted to be simultaneously transversely moved by interconnected worm shafts 13 and 14, respectively. Across the stationary frame, warp threads 15 extend, being supplied from a warp beam 16 and a cooperating beam 17 adapted to receive a finished rug or fabric. The form of the invention here shown is powered by a suitable electrical motor 18 or its equivalent, a main drive shaft 19 being driven thereby, from which chains or other driving means extend to the various shafts of the device, as will be hereinafter described. Associated witlrthe main frame, suitable heddles 20'are provided for guidin the warp threads 15.

The neec le assembly of the present invention includes a pair of co-operatingneedles 21, the upper ends of which are recessed to provide thread-engaging hooks at the extremities of the needles. The modified form of the needle, as shown in Fig; 37, is pro- 'vided with a downwardly-extending prong 21A, which serves to provide an improved grip of the thread by the needle. The needles 21 are united for IGSPQCtlK'G pivotal movement by inwardly-extending apertured cars 22, the apertures of which. receive therethrough a supporting and pivoting pin 23 mounted upon a transverse vertically-reciprocati11gshaft 24. The shaft 24 extends through vertical guide apertures 25 of the movable structure 12, one side of which is preferably provided with extended guide flanges 26 to insure proper alinement and guided movement of the shaft 24. Externally of the structure 12, the ends of the shaft 24 have mounted thereon depending links 27 which extend to operating wheels 28 mounted upon the extremities of a transverse shaft 29. Vithin the sides of the structure 12, the shaft 29 is provided with a gear 30, which enmeshes with a driving gear 31 slidable on and rotatable with a transverse drive shaft 32, one end of which is driven by a chain 33 from the shaft 19, the relative size of the gear connections being such that the shaft 29 is operated at twice the speed of the shaft 19, whereby the needles '7' will move upwardly and downwardly twice during one revolution of the shaft 19. The lower extremities of the needles are provided therebetween with a camming wheel 34, the shaft 35 of which passes there-through. The

needles being indicated in Fig. 5.

structure 12. The guide way 36 is angularly disposed, the arrangement being such that its upper extremity is spaced from the straight vertical path of the shaft 24, so that when the shaft 24 moved upwardly, the lower end of the needles is moved away from the shaft to tilt the upper end of the needles forwardly, the forward tilted position of the The arrangement is such as to provide for the needles a straight upward movement terminating at its upper extremity in an arcuate forward tilting path, from which they pass downwardly into the straight lower movement of their cycle.

For pivotally moving the needles, a spreader assembly, as will be hereinafter described,

is provided, and in conjunction therewith the free end of the shaft 35 includes a disk 38 having extending fingers while the structure 12 has a bifurcated arm 40, between the furcations of which a pivoted finger 41 is mounted, shown in detail in Fig. 11. The

first cycle, the wheel is turned as indicated in Fig. 19 to bring the ends of the needles together. Theyare retained in this position by the cam wheel until the end of the second cycle, at which time the wheel is again rotated by contact of the lingers 41, to ermit 3 1 the needles to assume the normal para lel relation as shown in Fig. 17.

For selectively holding a plurality of short lengths of variously colored threads for engagement by the needles during the forward movement in the arcuate path of their first cycle, a bobbin assembly is mounted over the warps in the upper transversely movable structurell'. The bobbin assembly, as shown more clearly in Fi s. 2 and 5, includes a plurality of bobbin disks 42, each of which has an angular collar 13 mounted upon a similar angular sleeve 44. The disks 42 include a plurality of pairs of bifurcated thread-holding fingers 45. 5 The bobbins are encased within a housing'46, the rear extremity of which extends over an extension of the sleeve 44. The housing 46 and the bobbins therein are slidably mounted on the sleeve 44, the assembly being longitudinallymovable in response to pivotal movement of a cam-0 erated lever 47, as will be hereinafter descri ed.

For selectively movingthe bobbin assembly in accordance with a predetermined design, the rear end of the sleeve 44 is provided with a plurality of recesses 48, within which selectively operated pivoted Jaws t9 maybe received, a'pair of jaws being provided for each of the recesses 48. By refer .with'a depending link 51 of a rocker arm 52.

The rocker arm 52 is centrally supported, as at 53, from the structure 11, its opposite end being associated with .links 54, the upper end of which is'joined to the intermediate portion one of a plurality of levers 551. The forward ends of the levers 55 are'pivotally joined with the vertical portion of the structure 11, while the rear extremities are provided *ith depending fingers 56, which normally rest upon a fixed pattern plate 57 supported on anapertured stationary table 58 of the stationary structure 10. This arrangement is such that as the upper structure 11 moves transversely of thedevi'ce, the registration of one of the fingers 56 within one of the aperturesof the plate permits the lever to drop downwardly, thus dropping the link 5%, pivotally moving the. rocker arm' 52, and raising the link 51 to close the jaws 49 within their particular recesses, the closed position of the jaws being shown in Fig. 13.

For raising all of the levers 55 to disengage any of the fingers 56 from the apertures of the plate 5?, thus to permit transverse movement of. the structure 1 1 over the device, a pusher bar 5-9 is provided, which extends vertically I at the rear end of the machine, its lower end having a wheel 60 in contact with a cam 61. The shaft 62 of thecam 61 is driven by the main shaftlS) through a chain drive 63 at one-half the speed of revolution of the shaft 29. The arrangement is thus seen to be such that during each two cycles of the needles, the pusher bar 59 moves up at once to hold the fine'ers out of engagement with the plate 51, so, as to permit transversemovement of the structure 11. The position of thecam G1 on its shaft 62 is such that the needles when inthe position at the end of their two cycles are downward, whereby the movement of.

the upper and lower structure will not interfere therewit Driven by the chain 64: from the shaft 62, a c" shaft 65 is provided, the cam 66 of which contact witha roller 67 at the upper end of the lever M. The position of the cam with respect to the cam 61, is such that the lower end of the lever 47 urges the bottom sembly forward "when the levers 55 are lby the pusher bar 59. When the pushmoves-downward, the registration of one of-the' apertures of the plate .57 with one move back until the striking of the rear ex-v of the fingers 56, permits that fingerto move 1 further down, thus closing the aws associated therewith. At the same time, the cam E66 rotates to permit the forward movement of the upper end of the lever 47 under the influence of its associated spring 68. The forward ,movement of the upper end of the lever i7 moves rearwardly its loweriendflhus moving rearwardly .the bobbin assembly The rearward movement of the bobbin assembly is, however, stopped bythe jaws 49 received within their recess. If the forward jaw e9, as shown in 2, is closed by the dew. rd movement of its lever 55, n0 movementor I If, however, one of the other of the levers were lowered by registration of its finger with one of the apertures of the plate '57, the bobbin assembly would be free to tremity of the housing T6 with the jaws d9.

his movement would bring a different one of alinement for engage--- the bobbin disks into ment of the threads carried thereby with the needles. This arrangement is seen to be 1 that the apertures of the plate .57 pro vzde selection of the thread moved by the needles. Thus byproviding variously colored threads on the bobbin disks, various de- 5 is may be automatically provided by configuration of the plate 57.

For rotating the bobbin platefrom which thread has been taken in; prior movement of the needles, the sleeve hl is provided with an r 1 inner rotatable and longitudinally fixed shaft 69. Intermediate the ends of the shaft 69, afiXed angularly faced nut/('0 is mounted, secured for rotation therewith The nut 70 forms a continuation between the forward and rearward ends of the sleeve, but 1s rotatable with respect thereto by IOtflt-ILOH.

the bobbin assembly will take place. 2?

y a pin 71.

move over the sleeve 44, the operating one I thereof willbe engaged by the nut 70 and upon rotation of the shaft 69, the bobbin will I be rotatech v For rotating the shaft 69, its forward end is provided with a sprocket wheel 72, having a plurality of extending fingers 73. Associated therewith a transverse shaft 7a is pro vided, driven by a chain at a speed equal to the speed of the shafts 62 and65. Sli ably mounted on the shaft 74for rotation therewith, a sleeve 76 having an extending finger 77 is mounted. The sleeve is mounted for sliding movement on the shaft 74:, with transverse movement of the upper structure 11, by end col ars 78 mounted on the upper structure. The arrangement is such that upon rotation of the shaft 74, the finger 77 will. strike one of the fingers T3 of the iii) ' across the warp threads.

sprocket wheel 72, to give the shaft 69 a partial rotation whereby the next adjacent pair of fingers of the rotated bobbin disk will straddle the arcuate upper path of the needles so as to provide thereacross a thread to be received thereby. The position of the finger 77 is such that the rotation of the bobbin is just after the completion of the rearward movement, if any, of the bobbin assemblies, so that rotation is given to that bobbin from which thread is to be taken by the needles.

By referring more particularly to 1, it will be seen that the device has plurality of warp threads 15 extending thereacross. The upper and lower structures are thus de signed to move simultaneously across the device so that the needles act to tie knots of thread taken from the bobbin over adjacent warp threads to form a. transverse row of knots across the warp threads, the warp being then moved and the upper and lower structures reset to again tie a series of knots For transversely moving the upper and lower structures simultaneously, the threaded upper and lower I shafts 13 and 14, respectively, are provided.

By referring to Fig. 14, it will be seen that the rotation of the threaded shafts is provided for by a cam 79, which is mounted on the end of a Shaft 80 driven by a chain 81 from the shaft 74, at a speed of rotation equal thereto. The cam 79 vertically reciprocates a shaft 82, which is provided with upper and lower links 83 and 84, respectively. Each of the links is provided with pawls which engage the ratchet teeth of ratchet wheels 85 and 86, rotatably mounted, respectively, upon the shafts 13 and 14. Mounted upon the upper and lower structure, spring-urged blocks 87 are mounted, the blocks having threaded surfaces engageable with the threaded surfaces of the shafts, as seen in detail in Figs. 14 and 16. The arrangement is such that when the blocks 87 engage the threaded surfaces of the shafts, they are moved transversely thereof by a worm drive to cause simultaneous transverse movement of the upper and lower structures. ,lVhen it desired to speedily move the upper and lowerstructures, for instance, at the completion of the formation of one row of knots, tl e hand lever 88,is moved which rotates with it a toothed gear 89, on either side of which are segmenta gears 90 engageable therewith. The segmental gears 90 which are partially rotated by movement of the handle 88 have associated therewith, finger-s91 which engage buttons 92 on the shaft 93 of the block 87 thus moving the block away from the threaded shaft against the tension of the spring 94, whereby theupper and lower structures are released fromthe threaded shafts and may be moved manually. The configuration of the cam 79 is such that the threaded shafts are rotated just as the needles are starting upward on theirfirstcycle and before any of the other cams have operated. Thus the structures are moved prior to the longitudinal movement of the bobbins on their rotation and prior to the movement of the needle spreader and knot jaws, which will be hereinafter described.

By referring to Figs. 23 to 29, inclusive, of the drawings, it will be seen that the needles first move upwardly on either side of one pair of warp threads. After the heads of the needles are passed above the warp threads, it is desirable to spread the heads apart to provide for their securing of a thread from the bobbin in position thereover. The intermediate pivotal connection of the needles provides for such movement and, as indicated in Figs. 17 and 18, it will be seen that the cam wheel is in the initial movement of the needles in proper position to permit such spreading.

A needle spreader and knot-moving assembly is provided, as shown more clearly in Figs. 5 to 9, inclusive, and 15. As shown in Fig. 15, the assembly includes a rigid yoke 95, including a rearwardly extending shaft 96, to the rear end of which is attached a spring 97, which normally urges the whole assembly forwardly. The movement of the assembly is controlled by a rocker arm 98 mounted upon a shaft 99, the upper end of the rocker arm 98 being provided with a roller 100, which bears against the face of a cam 101. The cam 101 is rotated by a chain 102 driven from the shaft and at a speed equal thereto. The configuration of the cam is such that the lower end of the rocker arm 98 is forced rearwardly holding the spreader assembly out of action until the needles are in fully raised position. The cam has by this time rotated one-fourth of a revolution, which permits the assembly to move forward "just enough to have the spreader finger 103 in position to cam apart the upper ends of the needles after they have passed between the warp threads, such position being indicated in Fig. 18. As the needles move downwardly, the cam 101 is rotated to move the spreader again rearwardly a short distance, so that upon the next upward movement of the needles, the upper ends will be forced by the cam wheel 34, as hereinbefore described, and the needles will passbetween the two warp threads which were previously between the two needles. This upward movement of the needles is indicated in 29, 30 and 31. The conformation of the cam 101 is such that toward the end of the second cycle, of the shaft 96, andrare urged together: by a spring 107. i

' In the previousmovements of this assembly, the ends of the jaws have been forward of the knot. As the spreader is withdrawn thejaws are brought back past the knot and forward movement thereof brings the aws.

into en a ement with the ends of the knot whereby thefiends are secured between the spring 10 1- and its associated jaw 105; The

whole yoke then moves forwardly and a push-- er block 108 associated with the jaw 105' to which the" spring 101 is secured, pushes the knot forward on the warp in, position with the knots-previously formed. The block 108 depends'from its associated aw 105 by a do pendingsupportingarm 109. The spreader 108 is-supported by an upwardly extending arm 110 to be in alinement with the upper ends of the needles'when the'needles are in their upward position. 7 For controlling the] pivotal movement of the 1aws, a dependlng finger 112 carried by a supporting block 113 on one of the j aws,=is arranged to move over a cam surface 11 1 supported {by the upper movable frame. The jaws are horizontally pivoted to the forward extension 106 of the shaft 96,.as at 115, whereby, as shown in Fig. 7, they may ride upupontheknots previous 1y formed to disengage the end of the new knot from. the'jaws before the new cycle'of the needles or pusher and spreaderassembly has moved rearwardly' to the positlon shown in Fig. Q'by the cam-101.

For cutting the threads on the bobbin disks between. the fingers 45, a scissors device'is provided,as shown in Fig. 1, the scissors in cluding a'fixed jaw and a movablej-aw, The;

movable jaw is provided with an operating extension 125, the rear end of whichisreceived within an eccentric groove of a drive wheel 116. The wheel 116 is drivenby a chain 117 at the same speed as the cam lOll and acts to close the jaws of the scissors to cut the thread jus'taafter the bobbins have been turned by the. gear 72. The arrange;

ment issuch that: prior to the taking of a thread from any vone of the bobbindlsks by the needles, the thread in the next adjacent span is cut'so that at all times the threads are cut for selection, byl-the'needl'es. *In the original positioning of the device, thethreads are all outv along the rear s de of the bobbin at the place where the scissors are provided.

' Thus the bobbins are freepto reciprocate'past the scissors andafter turningthe scissors operate to cut t-he new thread'of the bobbin wh ch has beenturned.

In thev operation of the device, starting i from the Zeropositionof the apparatus,it will be seen that the needles are in down-' ward position; By operation of the motor 18, the'shaft'29 is operated at twice the speed the other shafts, all ofwhich operate at the same speed. As the needle starts to move up and before it has reached the warp threads 15, the cam 79moves to turn the shafts l3 and 14, whereby the upper and lower structures 11 and '12 are moved arpredetermined'distance across the loom, thusarranging' the assembly whereby-the; needles will tie a knot;

on the warp threads next adjace-nt-to those I I from which the knot has previously been tied. With the needles still moving up and before they have reached the proximity of the bob-v bin-s, the camel is moved to lower the pusher bar. 59, thus permitting the registration of one of the fingers- 56 of one of the levers 55,

so that if the predetermined arrangement of aperturesof the plate 57 permits, one of the levers will be dropped, thus locking the jaws 19 thereof aboutthe registering recess inthe' sleeve 44. This position of parts being shown in Fig. 2.. The cam 66 then operates to permit forward movement of the upper, end of the lever 4'1, whereby the bobbins and bobbin carriage will be moved rearwardly under thelinfiuence of the; spring 68, until the rear end of the hobbinassembly strikes the jaws which'have been locked about the sleeve 4 1. c

The next step in'the operatiomwhich also" occurs prior to the movement of the needles to engagement with'th'e threads, is the rotation of the bobbin-rotating shaft 69, whichis controlled by rotation of the shaft 74 and actuation of the bobbin shaft. '69through the interengagement of the fingers 73 with the fingers 77". 7

.After the completion of these. movements, allof which are completed prior to the first half of the first, revolution of the needleoperating shaft '29, the needle continues its upward movement and the lower portion thereof movesbackwardly in the guideway 36, thus tilting forwardly the front end of the needles, whereby they follow the upward arcuate forwardly-moving path. At the upper end of such path the cam 101 operates to permit. forward movement of the spreader and jaw assembly, whereby the spreader 103 is: received betweenthe'needles, forcing them apart, whereby they pass through the threads as indicated inFigs. 23, 24 and 25, the move- Inent being indicated in Figsjoand 26. The

- needles then'continue' their downwardmovement, as indicatedm Figs. 27 and 28, andhere'inbefore described, releases the needles and they lower to the original zero posi-f .tion. During such lowering, the cam 101 formed, as indicated in Fig. 30, is pushed forwardly to abutting relation with the prior formed knots. The jaws are then retracted by the enlarged portion ofthe cam 101 and the whole machine is again in the zero setting. At the expiration of one complete transverse travel of the structures over the device, the lever 88 may be moved to disengage the threaded nuts from the threaded shafts and the structures may be manually returned to the original position. At the same time, the warp is moved as by the structure indicated in detail in Fig. 20, the beams 16 and 17 being provided with ratchet wheels 118 and 119, respectively, which may be engaged by dogs 120 carried on elongated arms 21, the link 122 thereof being adapted for actuation manually by a handle 123. Obviously, automatic means in the form of a cam, may be provided for moving the beams and for resetting the structures on the initial side of the machine.

The forming of the knots in the form and by the operation indicated in Figs. 23 to 32, inclusive, is only one form of knot which may be tied by the present invention. The so-called Chinese knot may be readily formed by the device as indicated in Figs. 33 to'36, inclusive. In the formation of this type of knot a mere variation in the configuration of the spreader and needle operating cams is required.

From the foregoing it will readilybe seen that the invention provides a novel and improvedknot-forming loom, and for automatic operation of the device in accordance with a preconceived design, the selection of colored threads from the various bobbins being in response to the preformed apertured plate 57.

It will be understood that the invention is not confined to a device utilizing single bobbin and single needle assemblies. A plurality of such assemblies may be used, so that in a singleo'peration of the machine a plurality of knots may be formed at one time.

It will be further understood that the in-' vention is not confined to the specificstructural details set forth, but that numerous changes, modifications and the full use of equivalents'may be resorted towithout departing from the spirit or scope of the invention as outlined in the appended claims.
